Unfortunately Nikon does not test the SW very well before releasing.
In Capture NX-D the Tool Buttons in the Edit Palette (like NR, Camera and Lens Correction, Perspective Control etc.) now only work if View Mode is set to “Image Viewer” and not in “Thumbnail” or “Preview” mode. Caused a lot of frustration as this worked in the previous version.
Genrally Capture NX-D is a very nice tool with probably the best RAW converter around for Nikon images, so it is such a a shame that Nikon is so sloppy before releasing a new version.
